The study course is fundamental to the calculation of stationary sinusoidal processes in circuits with linear elements - resistive, inductive and capacitive elements, ideal transformer. The symbolic method is used for calculating harmonic processes in the frequency domain. The study course looks at how to calculate amplitude and phase characteristics of different circuits, calculate complex power. The study course covers the theory of circuit calculations as well as laboratory measurements and circuit calculation application of SPICE based electronic circuit simulation software LTspice and MATLAB for numerical calculation techniques and simulations of circuits.
